The patch looks good to me.

I like this approach better than using a larger value closer to the
overflow (e.g. one week) and stepping the clock back automatically
when the clock reaches that time, but I suspect it might possibly
break more tests (or any unusual applications messing with time) as a
much larger interval is now EINVAL.
